If David Letterman can put out a Top Ten list night after night for decades, we can certainly make it all the way to 10 in our chronicles of the California High-Speed Rail debates. As a reminder, this is No. 8 in a series on the most ambitious and consequential infrastructure project now under consideration in our infrastructure-degraded land. It is the plan for a north-south California High-Speed Rail system, which had its genesis before Jerry Brown’s second coming as California’s governor but is now his signature project as he runs for reelection to an unprecedented fourth term. For previous installments see No. 1, No. 2, No. 3, No. 4, No. 5, No. 6, and No. 7.

Early this month, a three-judge panel of a California state appeals court gave the project a significant boost, by overturning a lower-court ruling that had blocked the system's major source of funding. There are still more legal challenges ahead, plus debate about the plan in this fall's California election; plus ongoing sniping between the most influential Democrat in California, Jerry Brown in Sacramento, and the most influential Republican, House Majority Leader Kevin McCarthy in Washington. For now, California HSR chugs ahead.

Here's a guide to upcoming installments. Today we'll hear a range of questions, complaints, fears, and outright denunciations of the system, drawn from mail that has arrived in the past few weeks. In the next installment, No. 9, we'll go into some further environmental, financial, and land-use aspects of the plan. Then in No. 10, I'll offer my unified field theory on why the 90 percent of Americans who don't live in California should care about the plan, and why I think it can be an important step for the state that has long been most influential in setting technological and environmental standards.

Also as an upcoming guide: We are continuing our American Futures journeys, including right now in Allentown, Pennsylvania, where we are meeting the Marketplace team tomorrow. Soon after Labor Day we'll be back in this space with reports on the cities we have visited over the summer, from Duluth, Minnesota to Winters, California, and points in between.

For now, the HSR mailbag.

1) "Ridership forecasts are simply unbelievable." This is from someone with extensive technical experience in high-speed Maglev train projects.

I  have followed your articles on CAHSR with great interest. I am not a fan of the project and would like to make the following observations—

Your concern about what is going to happen without HSR in California is well placed. Congestion on highways and at airports is bound to reach epic proportions. However I do not think the present plan for HSR is going to avert this problem.

Ridership forecasts are simply unbelievable. Currently there are about 15 M annual person trips between the LA Basin and SF Bay areas by highway and air, about evenly divided. This is highly unusual. In the US for a trip of this length ~400 miles where there is good air service, the proportion of highway trips is generally much lower. We are comparing a 6 hour road trip with a little over 1 hour air trip. The average airfare, $130, is also unusually cheap, about half the airfare between Washington, DC and NYC for a distance roughly twice as great.

So I ask, why with a rail trip of over 2h40m and fares 50% of airfares, why would 9.5 M LA Basin and SF Bay travelers in 2030 choose rail over highway and air?

Ah! but you say, a trip by air includes getting to the airport and perhaps an hour or more of being hassled over security, et al. But wouldn't the same be true for HSR rail if it becomes a reality?

Firstly there are 5 airports in metropolitan LA and 3 in metropolitan SF serving the California corridor. It would appear that an airport would be closer at hand than a rail station. Don't imagine that TSA would miss the opportunity to hassle rail passengers. Already Amtrak imposes onerous restrictions on its passengers. [A colleague] attempted to buy tickets in advance at DC Union Station for himself and his wife, and was told the station agent could not sell his wife's ticket without her being present and showing ID. (However he was directed to a ticket machine nearby where he was able to buy both tickets without ID and with what could have been a stolen credit card.)

Think about it. Why would a traveler in 2030 elect to take the HSR rather than drive, when at present he is willing to spend 6 h on the road rather than fly? One reason of course is that the road trip will take more than 6 h by then due to congestion, but also getting to a rail station will also take much longer in a crowded metropolitan area.

As for the projected 28.8 minus 9.5 M riders between intermediate points, there is even less reason to switch from auto to rail. Trip times are much shorter and you have a car at both ends. Unlike the Northeast corridor, there are relatively few folks living in the towns between the endpoints. And from discussions with these folks I found that most live in these smaller places because they hate LA and SF and have no reason to go there. [JF note: OK, maybe, but they often have to go to either of those cities for business, entertainment, etc.]...

Finally the cost of $68 billion is excessive. It amounts to $200M/mile for the undeviated 344 mile distance between LA and SF. Of course the actual rail line is round-about to avoid tunnels and serve those small towners in between. However the proposed Japanese maglev system between Tokyo and Nagoya is estimated to cost $5 trillion yen/286 km, or $167 M/mi. It involves over 142 miles of tunnel! Also the speed is substantially greater than CAHSR. So avoiding tunnels does not seem to save on US construction costs.

Perhaps we should let the Japanese build the system, but they would likely choose maglev over rail, despite the fact that they operate one of the few highly profitable high speed passenger rail systems in the world.

Incidentally I do not hate rail. I worked for the Federal Railroad Administration for over twenty years, and I take rail whenever I can, including driving from Palm Springs to San Bernardino and catching Metrolink to LA whenever I travel there. And I encourage others to take the train whenever possible.

2) No-good, terrible, very bad idea. From an engineer in the Central Valley:

Bad, bad, bad. In no particular order:

·         The HSR Authority and anybody associated with this cannot be trusted. Past cost estimates have ranged from $40 billion to $100 billion and now down to what, $80 billion? In other words, the cost estimates are determined by political expediency. Actual costs are, of course, likely to be far higher. We’re being lied to, openly.

·         HSR works best between cities with lots of mass transport. That is probably true for SF, certainly not for LA. Whatcha gonna do when you get to downtown LA and you need to be 50 miles from there? Rent a car and join the masses stuck on the freeway. At least LA has a few airports that might get you closer.

·         Business travelers now can make trip in one day between SF / LA. It’s a long day, sure, but it’s feasible because aircraft travel is so fast.  Not so with HSR, so many business travelers will shun it. Families then? No. Yes, driving is longer but your cost for 4 people is simply going to be much less driving than paying for 4 tickets. And you’ll have your car, instead of an additional rental cost.

·         It’s being built in a corridor that doesn’t have a demand problem (down the Central Valley), and even if there were, another lane on Interstate 5 each way would fix that. I’m guessing a substantial part of any Central Valley congestion is freight trucks, which HSR won’t do a thing to solve.

·         It bypasses, and has no plans, to connect to Sacramento or San Diego. Ridiculous.

·         Think airport security is bad? HSR will require a very ugly fence on each side of it. Imagine if someone snuck over and place a small wedge on a track. How you gonna protect 500 miles of rail?

·         California (and maybe the nation) can’t build a damn thing right. CalTrans went $2 billion over on building the new Bay Bridge span (1/2 of the total span), and it has an ever-growing list of serious problems. It’s not foolish to question if the new span will, in an earthquake, remain standing. I’ve seen the same gross but genial incompetence in my government agency. There’s simply no accountability.  Oh, Governor Brown’s response to the Bay Bridge’s cost and structural problems? “Shit happens.”

The problem with the California HSR is the proposed project. HSR in general is fine, when done correctly, and it could be done correctly in California, but the current project pretty much guarantees it won’t.

Instead why not build in corridors of proven demand? That would be Sacramento-Bay Area, where the Amtrak Capitol Corridor runs now. An HSR there would be fantastic, and if it failed at least wouldn’t cost a hundred billion dollars or more.

3) What about the earthquakes? A reader in the Midwest is one of several people to write in with this concern:

I lived in Marin County for quite a few years, including the time of the Loma Prieta quake.  I have also had the dubious pleasure of living through some rather substantial quakes in Tokyo, China, and Indonesia during my travels.

I know that living in the seismic zone has not prevented Japan from building a successful high speed train such as the bullet train from Tokyo to Osaka (which  I have taken several times—and is a great ride), but I wonder what real dangers exist for a California route that would seem to cross over the most  seismically active and dangerous portions of the state.

I credit the Japanese for doing the most serious anti-quake engineering in the world, but have some concerns about whether Californians would accept the costs necessary to make such a project safe during relatively large quakes.

4) "A boondoggle and a gigantic waste of money." From a reader in California:

I used to live in Europe, about 10 minutes walking distance to a major HSR line. I also live within walking distance of Caltrain in California and take it frequently.

I think Americans like it because it is a fun and convenient way for tourists to travel between a few make tourist destinations when they have no schedule to meet. Practical, cost effective transportation it is not.

High speed trains run rarely enough that you can't take them close to appointments. Delays mean that you often need to leave long layovers to make sure you make a connection. In the end, going by HSR often takes 2-3 times as long as driving. Trains are also much more expensive than long distance buses or flying.

That is under ideal European conditions. Between SF and LA, you have a much smaller potential ridership, a worse network of feeder lines, and higher costs.

HSR in California is a boondoggle and a gigantic waste of money. You're likely subsidizing each potential rider with trends of thousands of dollars construction costs alone, plus more subsidies in operating costs. That's not even counting the expensive union labor for construction and public union labor for operating the trains. HSR is a scheme by which the average tax payer has to pay for the convenience of a small number of privileged and wealthy city dwellers, give contracts to a small number of well connected corporations, and pour money into the hand of unions and union workers. HSR represents political corruption, crony capitalism, and vote buying at its purest.

5) Back to Maglev. From a person I know in Washington, who has worked for years on Maglev projects.

As you know, I advocated for the use of maglev technology over HSR for years. The reason the Central Japan Railroad is going with its superconductor maglev technology, at their own expense, for their new Chuo Shinkansen line is not just because of faster top cruising speeds, but because of the significantly lower maintenance and correspondingly higher "system availability" that maglev technology offers them. Lower annual maintenance costs means lower life cycle costs for the entire system, which is why CJR chairman Yoshiyuki Kasai is deploying this technology at the company’s own expense—yes, without government funds.

Too much is made of speed, though speed is important. But, to be able to travel at high speeds with relatively low maintenance costs allows operators to not require annual operating subsidies from tax payers, something government run railroads are not overly concerned with. In other words, this technology shift creates an environment that encourages private investment in high-speed ground transportation because profits are not only possible, they are highly likely in any reasonably busy corridor.

Aside from the Wenzhou-Hangzhou viaduct crash in July of 2011, the Chinese slowed their HSR trains down from 220 mph to 185 mph because they also learned some laws of physics: for each speed increase of 10 mph over 185 mph, train maintenance costs double. Not only do wheels get replaced more frequently, but rails too.

6) Sobering lessons of experience:

I'm an instinctive supporter, as you are. But life the Bay Area has thrown a couple of cautions at me:

1) the Bay Bridge—only 24 years from earthquake damage to replacement, with an endless string of engineering flaws and delays discovered along the way. And a busted budget. Is HSR management likely to be better? Otherwise, the thing will take a century.

2) BART to SFO: estimates of ridership were grotesquely inaccurate. They've had to radically reduce the number of trains. Now I voted for and love BART to the airport. Works great for me (makes it SFO to LAX instead of OAK to BUR). And various friends were employed in the project for a decade. But the precedent seems dubious.

7) "Just raise the ticket prices to pay for it." From a reader on the East Coast:

You may recall that, in 2010, Chris Christie scuttled a plan to build two new tunnels under the Hudson—I'm a NJ resident and a sometime commuter, so I was paying close attention.

Christie based his objections on the likelihood of cost overruns (which would have to be borne by the state); those who supported the project, like the NY Times, argued that he should take all cost estimates at face value. Voters, who have had a long, long experience with cost overruns (you might recall the Big Dig in Boston ...), inclined to Christie's side of the argument. After all, we'd just spent significantly more than half a billion dollars to feed the egomania of Frank Lautenberg via the "Frank R. Lautenberg Rail Station at Secaucus Junction".

But there are perfectly good reasons to criticize such projects from the Left. The "Access to the Region's Core" project was originally estimated to cost $8.7 billion; by the time it was cancelled, that estimate had risen to $11 billion. Half the original funding was to come from NY and NJ (mostly NJ). So the general tax revenues of the state would be used to construct boutique travel benefits for the highest-earning people in the state, while simultaneously increasing travel costs for everyone via gasoline taxes and toll increases.

Why should the bottom 60% or so be required to pay for a shiny new toy for the top 40%? Certainly, as one of the latter class, I can appreciate that I'm arguing against my interests ... but would it be fair?

So, if you really want HSR in California, all you have to do is argue that the HSR ticket prices must reflect the full cost of the project.

8) "It won't fix climate change." Finally for today:

My understanding is that California agriculture uses about 80% of our water but provides only 5% of economic output. Ongoing drought and shifts in federal policy are only making water more expensive. So whatever the ostensible productivity of that land, the price of water means that the future of California's economy will necessarily continue to shift toward the cities. (Hence the farmland-eating sprawl you lament.)

Thus the question of "what do we do with the Central Valley?" looms ever larger. As you know, unemployment rates are terrible there. I interpret the HSR mostly as a jobs plan. I can believe that infrastructure programs can have unexpected benefits. But the systemic trends hurting the Central Valley go much deeper than transportation. The HSR won't fix climate change.

Thanks to all for writing. More to come.
